Wizzer --
Sheesh, what a mess but verrrrryyyyyy interesting for ground conductivity
if saltwater. I would just put a big form in the "ground" and wheelbarrow or
pump the concrete in. Either a wooden form or a big, short section of
Sonotube would work. Kind of messy but not too many other choices. An
electric pump might enable you to evacuate most of the water which would be
helpful. Keep the concrete/swampwater slurry from running into the swamp
would be a good ecological thing to do. This is the other thing a tower base
does -- keeps the tower from sinking in the ground.
BTW, what is G10? Is it an insulating material in the legs or what?
Good luck, Wiz -- Steve K7LXC
